There's some commercial artist that does portraits of indians in profile, wrapped in blankets so they don't have to have detailed bodies. It's always the exact same face, the only variation is that it's either facing right or left. I saw them on the walls of offices a lot when I was in Tucson. I thought they awful. I just tried to google up an example and failed, so you'll have to forgive me... But the profile on the side of this bus looks almost exactly like every indian in every one of those paintings.
